Will it sound good before it blows up?
The problem was the bait and switch. Unfortunately you have ended up with a speaker with three woofers in parallel. That really ups the ante as far as the robustness and stability of the amps driving them. Any time you get an impedance below 4 ohms, think dollars for amps. I have not found the phase angles for those speakers yet. If I can not find it, I will have to come and measure the curves.
The issue is this. Every time you increase increase volume by 3db you double the power the amp has to deliver to the speakers. It gets worse, as to give that power of 3db the current in the output devices doubles and that means the heating effect in the devices is squared. It is heat that kills and blows up the amps.
So, I have to think about this. You have dug a bit of a hole as powering powerful low impedance speakers has large dollar signs attached.
Try and get out of that Emotiva purchase and turn the volume down until we can come up with a plan that makes sense.
